When the player uses Oscar's Grind system he plays hands as a series, with an aim of coming out of every series with a net win of one-unit bet at least. It’s a bit more conservative than the Martingale system as the increase in bets isn’t so dramatic and the frequency of increases doesn’t happen very often and the outcome can be positive if the player has got the adhesiveness and a sufficient bankroll to play each series.
The player starts with a one-unit bet. If he wins, he gets a one-unit profit, and that series ends. If the hand loses, the bet stays put until one more hand wins, and this time the bet is doubled. This continues till enough hands are won to recover all hands that have been lost, and end up one unit ahead. The next hand starts a new series.
1 lose 1 lose 1 lose 1 win 2 win 4 win
Oscar's Grind is not bad.
The player will be able to get small wins in the short run. There is little chance of big wins or big losses.
However, there are some drawbacks to this system. First of all, a player may be "locked" into a very long series. The system requires a loser to win several hands before he recovers all preceding losses and not to stop playing till the full recovery. The second disadvantage is that to keep track of the net balance during a long series of hands needs much concentration. This betting system may distract the player from basic strategy that can certainly result in inevitable losses.
